内部整数repres。

问题描述

是内部表示的所有整数只是位向量吗？

解决方案

ISO C没有定义内部如何表示整数。 br />

这不对。这甚至都不错。

不一定，除了位域和变量类型

unsigned char。但是，无符号整数

类型所需的语义使它们就好像它们如此表示一样。

是的。计算机将所有内容都表示为位向量。


好​​吧，有人可能为百灵鸟制作了一台三元计算机，但是C / /
指定一个字节由一个序列组成比特，所以它的C

实现必须这样做。

are all integers represented internally as just bit vectors?

解决方案

ISO C does not define how integers are represented internally.

Not necessarily, apart from bitfields and variables of type
unsigned char. However, the required semantics of unsigned integer
types make them act as if they were so represented.

Yes. Computers represent everything as bit vectors.

Well, someone might have made a trinary computer for a lark, but C
specifies that a byte consists of a sequence of bits, so its C
implementation must do the same.
